Specification of Letters-Patent No. 3,150, dated June 24:, 1843.

To all whom it'maj concern Be it knownthat I, CHRISTIAN Burr, of Hartleton, Union county, State of Pennsylvania; have inventeda new and useful Improvement in Machines forTh-reshing Grain, Hulling Glover-"Seed; and for Cleaning the" Same,:whicli is. describedas follows, refer encebemg had to' the annexed drawings of IUD the same, making; part ofthis specification.

Figure 1 is a perspective view. Fig. 2 is a vertical longitudinal section ;1 Fig. 3*, one of the segment toothed plates used in forming the concave when th'e' machine is to be adapted to hulling clover seed; Fig. 4 the spiked guard Fig. 5, section of the" hopper of the clover hulling machine.

Similar letters refer to corresponding: parts. i l

The frame A is made of sufficient size and strength to contain and support the several parts hereafter described and forr'n resembles the frame of a fanning machine.

The concave B for threshing grain is made of bars of wood and armed with iron spikes the ends of said bars are inserted into segment grooves on the inside of the two end plates C. These end plates are cast with semi-circular grooves D on the inside to admit the ends of the aforesaid bars B forming the concave and those of the segment plates p when the machine is adapted for hulling clover seed. These end plates are also provided with flanges and bolt holes to admit bolts for securing them to the frame A and with concave seats for the journals of the cylinder to turn in. The bars forming the concave are prevented from descending too low in the grooves by stops placed therein.

The threshing cylinder E that turns in said concave is made and turned in the usual manner. The feeding hopper G by which the grain is introduced is made in the usual manner.

The cap H is likewise made in the usual manner except that it is provided with an opening closed by a hinged door I that is to be opened for the insertion of a hopper when the machine is to be altered and arrangedfor cleaning clover seed, and also with two inclined grooves for the introduction of an inclined board J for the purpose of directing the cloverseed &c. downward upon the screens when the conducting board and conveyer are removed.

A fan K for cleaning the grain is placed below the aforesaid inclined feeding board G surrounded partly by a semi-circular case L made like that of a common wheat fan, the

axleofwhichfan turns in boxes in the frame and extends beyond the sides thereof to receive a pulley for a band and a fly wheel M on the opposite end which also serves as a band wheel; said axle having likewise a crank formed in it from whichextends a pitnian rod N leading to the end of a Vibl'flt.

ing rod 0 attached by a loose joint at one of its ends to the inside of the frame on which joint it vibrates or moves horizon tallythesegment of a circle to the middle of which bar the vibrating or swinging frame the old method.

A3 straw conveyer R for conveying 0H the straw and for allowing the grain to descend through its meshes while the strap passes over them is placed at the rear of the threshing cylinder. The frame of this conveyer is composed of two bent pieces of timber or knees 6 connected together by a bottom board R between which knees are placed two revolving square bars whose gudgeons turn in said knees around which is passed a series of endless parallel straps or bands T, crossed at right angles by a series of parallel straight bars R secured to said straps or bands through which at their intersection are inserted spikes or pins for taking hold of the straw said bars being made to pass under small wheels or short rollers U turning on pins inserted into the sides of the aforesaid frame of the conveyer for shaking it. On the outer extremity of the journal of one of the revolving square bars is a pulley V for a band by which it is turned. The inclined board below the conveyer is placed at a sufficient distance therefrom to prevent theteeth touching it and also to admit the grain to descend to the receiver.

A horizontal conducting board Wis placed against the lower edge of the concave for conducting the straw to the conveyer.

The machine is fed and operated in the usual manner.

An oblong receiver X for receiving the cleaned grain is placed below the conveyer.

The machine to be adapted for the cleaning of clover seed requires that the aforesaid concave B should be removed-also the straw conveyer Rand a concave of plates 29 substituted that Will be adapted to the getting out of clover seed or separating it from the bulls made in the following manner. Six segment plates 29 are cast With teeth on the concave surfaces and tenons on the ends Which fit into the semi-circular grooves D on the inner sides of the before described end plates 0. The clover seed is separated from the hulls by the teeth of cylinder and con- I cave and ribbed on the sides for the purpose of increasing the rubbing surfaces. The door in the cap is raised and turned back out of the Way and a hopper it is inserted for feeding the machine or conducting the clover heads or hulls to the concave and cylinder for undergoing the rubbing operation in Which is placed a horizontal board or guard g for preventing the escape of the seed. The inclined board J is also added for the purpose of directing the seed and chaff to the screens. This is inserted into grooves made on the inner sides of the cap and in front of the threshing or rubbing cylinder. A spiked guard is also added to the cap at the front of the concave inserted in the segment grooved forming a continuation of the concave to prevent hard substances entering the concave. Boards 6 and fine screens 8 are inserted into the screen frame 6 below the sieves in grooves in alternate order first a board and then a screen for the purpose of more effectually separating the chaff and dirt from the grain. The clover heads are put into the hopper h and descend between the cylinder and concave Where they undergo the rubbing operation and When the seed is separated from the hulls. The Whole seed, chaff, dust, and dirt are then carried out at the rear of the concavethe lighter particles being blown away by the fan K While the heavier portions With the seed descend upon the vibrating screens the seed falling through the meshes thereof into the receiver X While the chaff and straw are shaken off at the rear of the screens. The inclined board 2 is for directing the blast from the fan more directly to the screens.

hat I claim as my invention and improvement and which I desire to secure by Letters Patent is 1. The combination of the conveyer agitated in the manner described With the threshing machine as set forth.

2. Also the arrangement of the screens constructed With boards placed under them in the manner set forth.
